Sold in five different packages, Power Support's latest film protectors have arrived with improvements -- and higher price tags -- for the iPhone 4. The most basic sets are the 2-Piece Crystal Screen Film Set ($20) and 2-Piece HD Anti-Glare Screen Film Set ($20), which each include two screen protectors and a white dust removal sticker than can be used to prepare your iPhone 4's face for installation of the film. Power Support touts the HD Anti-Glare film as especially well-suited to the iPhone 4's high-resolution display, and it does have the highest clarity and lowest prismatic effect of the films we've tested as of August 2, 2010, though it's very close to United SGP's version. Three additional packages bundle screen and iPhone 4 rear protective film together: a 2-Piece Crystal Front And Back Film Set ($20) has clear front and back pieces, while a 2-Piece Anti-Glare Front And Crystal Back Film Set ($20) swaps in the HD Anti-Glare screen film, and a 3-Piece Front And Back Film Set ($25, shown) has one of each type of screen film plus clear back film and two dust removal stickers. The latter three solutions can be paired with Apple's Bumpers if you want minimalist-looking coverage for the iPhone 4.
